Caracter��sticas da carca��a e alometria dos tecidos de cabritos F1 Boer �� Saanen

Com o objetivo de avaliar as caracter��sticas de carca��a e a alometria dos cortes comerciais e dos tecidos de cabritos F1 Boer �� Saanen, 35 animais foram abatidos ao atingirem 5, 10, 15, 20 e 25 kg de peso vivo (PV). A dieta dos animais foi composta de leite de vaca nos primeiros 49 dias e ra����o �� vontade do s��timo dia at�� o abate. Os cortes foram obtidos ap��s o resfriamento da carca��a e a perna foi dissecada em m��sculo, osso e gordura. O PV teve efeito linear decrescente no rendimento de carca��a fria e na ��rea de olho-de-lombo por kg de carca��a. Os pesos de perna, paleta e pesco��o em rela����o �� carca��a fria decresceram linearmente, mas houve efeito quadr��tico sobre o rendimento de costelas e lombo. O crescimento de paleta, pesco��o e perna foi isom��trico (b=1) ao do corpo, enquanto o das costelas e do lombo foi mais lento (b¹ 1). Os m��sculos da perna cresceram igualmente, a gordura mais lenta e os ossos mais rapidamente que a perna, enquanto o desenvolvimento da gordura subcut��nea foi mais tardio que o da intermuscular. Para obten����o de carca��a de 8 a 11 kg com rendimento superior a 44%, boa propor����o de m��sculo e gordura com menor perda durante o resfriamento, recomenda-se abater os animais com PV entre 20 e 25 kg, mas, se o objetivo for carca��a de menor peso, o abate dos animais deve ser feito ao final do aleitamento com aproximadamente 10 kg de peso corporal.

Frontal sinus recognition for human identification

Many methods based on biometrics such as fingerprint, face, iris, and retina have been proposed for person identification. However, for deceased individuals, such biometric measurements are not available. In such cases, parts of the human skeleton can be used for identification, such as dental records, thorax, vertebrae, shoulder, and frontal sinus. It has been established in prior investigations that the radiographic pattern of frontal sinus is highly variable and unique for every individual. This has stimulated the proposition of measurements of the frontal sinus pattern, obtained from x-ray films, for skeletal identification. This paper presents a frontal sinus recognition method for human identification based on Image Foresting Transform and shape context. Experimental results (ERR = 5,82%) have shown the effectiveness of the proposed method.

This study did evaluate the handgrip strength capacity of bull riding practitioners and recreational practitioners in order to obtain parameters of the muscular fitness of subjects undertaken this sports practice. Twenty right-handed subjects were grouped into bull riding athletes (10 individuals at AMT: 174.5 �� 5.2 cm of height, 78.9 �� 12 kg of body weight, 24.7 �� 6.1 years, and 13,8 �� 2.4% for body fat) and non-athletes (10 subjects n-AMR: 178.5 �� 7.3 cm of height, 81.2 �� 8.8kg of body weight, 21.7 �� 2.3 years, and 13.8 �� 1.9% of body fat). They were underwent to protocols of handgrip strength evaluation by a standard and specific dynamometry (simulating a bull riding posture) of right (DPD e DED) e left (DEP e DEE) hands. The dynamic force values from one repetition to maximum test (1RM) were either obtained in conventional load-based system for upper limbs exercises. The values were compared by the test-t for independent data, assuming �� ��� 0.05. The relationship between the values of strength from handgrip and dynamic exercises were drawn by Pearson correlation. The results of the AMT to DPD (43.8 �� 6.8kgf), DPE (39.4 �� 7.7kgf), DED (44.9 �� 5.6kgf), and DEE (39.8 �� 8.3kgf). For the n-AMT in DPD (47.0 �� 3.0kgf), DPE (42.2 �� 6.1kgf), DED (49.2 �� 1.5kgf), and DEE (46.2 �� 4.1kgf). Significant difference was observed between DED and DEE. The strength tests of 1RM at bench press (73.2 �� 12.0kg and 82.0 �� 12.0kg), arm-curl (45.2 �� 8.9kg and 43.8 �� 8.9kg), triceps pulley (67.0 �� 6.3kg and 72.0 �� 6.3kg), and pulley (73.5 �� 8.5kg and 73.7 �� 7.5kg) for groups n-AMT and AMT did not showed differences. Correlations were showed between all handgrip tests and elbow flexor force for AMT, and between DPD and elbow extensor, abductor, adductor and extensor of shoulder for n-AMT. influences to the performance of the force dynamometry. It could be concluded that handgrip force and dynamic strength of upper limbs did not were putative responses for bull riding practice.

A influ��ncia da carga imposta pela mochila escolar em alunos do ensino fundamental e m��dio: uma contribui����o para estudos ergon��micos

This cross-sectional study aimed to evaluate the load carried by students in primary and secondary schools, state Vespasian /MG, and quantify the percentage established between backpack weight and body mass of these young people carry every day. The study included 916 students of both genders. Ages ranged from 10-19 years. 541 students (59.06%) carried the load backpack ranging from 10.02 to 33.43% of his body mass. Students with younger age, female students and those who opted for the backpack model designed dorsal attachment tended to carry a load higher than 10% of his body weight. 224 (24.45%) students complain of back pain and shoulder. It was concluded that the cargo is inadequate from the point of view of biomechanics and ergonomics, especially for younger individuals and females, since they are in growth phase, and this exposes them to an overhead increased risk of spinal injuries, with consequent repercussions in adulthood.

Ultrasound Transient Shear Wave Elasticity Imaging for Tendon Tissue

Degeneration of tendon tissue is a common cause of tendon dysfunction with the symptoms of repeated episodes of pain and palpable increase of tendon thickness. Tendon mechanical properties are directly related to its physiological composition and the structural organization of the interior collagen fibers which could be altered by tendon degeneration due to overuse or injury. Thus, measuring mechanical properties of tendon tissue may represent a quantitative measurement of pain, reduced function, and tissue health. Ultrasound elasticity imaging has been developed in the last two decades and has proved to be a promising tool for tissue elasticity imaging. To date, however, well established protocols of tendinopathy elasticity imaging for diagnosing tendon degeneration in early stages or late stages do not exist. This thesis describes the re-creation of one dynamic ultrasound elasticity imaging method and the development of an ultrasound transient shear wave elasticity imaging platform for tendon and other musculoskeletal tissue imaging. An experimental mechanical stage with proper supporting systems and accurate translating stages was designed and made. A variety of high-quality tissue-mimicking phantoms were made to simulate homogeneous and heterogeneous soft tissues as well as tendon tissues. A series of data acquisition and data processing programs were developed to collect the displacement data from the phantom and calculate the shear modulus and Young���s modulus of the target. The imaging platform was found to be capable of conducting comparative measurements of the elastic parameters of the phantoms and quantitatively mapping elasticity onto ultrasound B-Mode images. This suggests the system has great potential for not only benefiting individuals with tendinopathy with an earlier detection, intervention and better rehabilitation, but also for providing a medical tool for quantification of musculoskeletal tissue dysfunction in other regions of the body such as the shoulder, elbow and knee.

Physical and psychosocial risk factors for musculoskeletal disorders in Brazilian and Italian nurses

As part of the international CUPID investigation, we compared physical and psychosocial risk factors for musculoskeletal disorders among nurses in Brazil and Italy. Using questionnaires, we collected information on musculoskeletal disorders and potential risk factors from 751 nurses employed in public hospitals. By fitting country-specific multiple logistic regression models, we investigated the association of stressful physical activities and psychosocial characteristics with site-specific and multisite pain, and associated sickness absence. We found no clear relationship between low back pain and occupational lifting, but neck and shoulder pain were more common among nurses who reported prolonged work with the arms in an elevated position. After adjustment for potential confounding variables, pain in the low back, neck and shoulder, multisite pain, and sickness absence were all associated with somatizing tendency in both countries. Our findings support a role of somatizing tendency in predisposition to musculoskeletal disorders, acting as an important mediator of the individual response to triggering exposures, such as work-load.
